Specification of Letters Patent. Application filed March 7, 1911.

Patented May 2, 1911. Serial No. 612,770.

To all whom "it may concern:

Be it known that I, CORNELIUS MonmsoN, a citizen of the United States, residing at Glasgow, in the county of Barren and State of Kentucky, have invented a new and use ful Churn, ofwhich the following is a specification.

This invention relates to devices employed in assisting in operating vertically movable members, such as churn dashers, rod drills, and some forms of pump rods, and the like.

The primary object of said invention is to so construct a device of this character that the vertically movable member may be easily and conveniently manipulated, the raising (iii said member being assisted by spring iucahsrand the descent/f said member being assisted wameight. a

With the abbve and other objects in view as will appear as the description proceeds, the invention resides in the combination and arrangement of" parts and in the details- .of construction hereinafter described and partly Supported by claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification,-Figure 1 is a side elevation of the complete apparatus, in section; Fig. 2 a top plan view; Fig. 3 a detail view, partly in section, of the plunger and its supporting mechanism; Fig.4 a detail view of said plunger and supporting mechanism; Fig. 5 a detail View of the supporting bracket; and Fig. 6 a modified form of dasher.

Referring to the drawings by characters of reference, 10 designates a base plate on which is positioned a cream receptacle 11. said base plate is a tubular upright 12 which receives the shank portion 13 of a bracket member 14, said bracket member. being formed with parallel spaced arms 15 and 16 Whichterminate in curved supports 17. It will be noted that said portion 13 is adjustable Within the tube 12, the same being held in its adjusted position by the thumb nut 18. i

The plunger mechanism consists of a shaft or plunger 19 to the base portion oi. which is secured a dasher 26, which is connected to the shaft 19 by the weighted sleeve 20. Arranged on the plunger 19 is a plurality of. sleeves 21 and22, the sleeve 21 being capable -tion of the plunger within end of the bracing the 22, together.

of adjustment on said plunger, being held in adjusted position by the' thumb nut 23. The sleeve is provided with the enlarged bore 22 which permits the ready reciprocasaid sleeve. Said sleeve is provided with the trunnions 24 which terminate in heads 24'; these trunnions are, when the device is in its operative position, adapted to restwithin the curved support 1'2 A coiled spring 26 is secured at one end to theeyes 27 carried by the lower sleeve 22, said coiled spring emplungei, its other end being secured to the eyes "28 supported by the upper end of the sleeve 21, the spring being of a gradual taper, its reduced portion being at tachcd to the sleeve 21. It will thus be seen that with the dcvicasuspended, as shown in Fig. l, the plunger is resiliently hung, the weighted sleeve 20' tending to overcome the tendency of the spring 26, said spring nor-- mally tending'to draw the sleeves 21 and It will thus be seen that it will require but a slight movement to reciprocate the plunger through the medium of the handle 28, the downward movement of the plunger being assisted by the weighted sleeve 20', the upward movement being assisted by the spring 26, and a constant and rapid reciprocation of said plunger being readily'attained with very little effort, on

the part of the operator.

Particular attention is called to the peculiar manner of resiliently supporting the plunger and to the fact that the tension of the spring member may be adjusted by means of the sleeve 21, thus increasingor diminishing the upward pull on the plunger and effectually regulating the stroke. It will also be noted that the bracket member may be adjusted to accomplish this same re-', salt and that when the device is not in use or when it is desired to disassemble the parts, the trunnious may be readily removed from the curved support 17."

The modification shown in Fig. 6 consists of the'weighted sleeve 29 from whiclrextends the arms 30, dasher 31. In this way the dasher itself is weighted,. the sleeve 29 and the arms 30 which are formed of metal, answering the; purpose of the weight 20, which is shown inthe preferred form.

In the form shown in Fig. ft, the plunger 19 is in two sections, the lower section to which the dasher is secured extending with which arms support't-he in the sleeve 21 and being held within said 'sleeveby set screw 21", the upper portion of said plunger being adjustably held in said sleeveby means of the set screw 23. This construction permits of the ready removal of the dasher for the purpose of cleaning the same.

The many advantages of a construction of this character will be clearly apparent,-

' )lun er a .wei hted daslier arran ed on one 1 g 2 g end of said plunger, a' plurality of sleeves arrangedon said plunger, one of said sleeves being secured to said plunger, trunnions secured to the other sleeve and supported by thearms of said bracket, and a spring coiled around said plunger, saidspring conmeeting saidsleeves,
